NUT-LOCK.

* Specification of Letters Patent.

Patented July 4, 1911.

Application filed December 2, 1909. Serial No. 530,911.

To all whom it may concern:

Be it known that 1, WILLIAM L. SPELLACY, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Nut-Locks, of which thefollowing is a specification.

This invention relates to nut locks designed more particularly for usein preventing the nuts from loosening on the bolts for securing togetherthe meeting ends of railway rails, but capable of general use as a nutlock, and one of the principal objects of the invention is to provide anut lock of simple construction, which will effectively prevent the nutfrom turning on the bolt and which will permit the readjustment of thenut whenever required.

Another object of the invention is to pro vide a nut lock comprising asomewhat rectangular plate of steel having a spring tongue benttherefrom, said tongue having a sharpened edge to bite into the innerface of the nut, to prevent its withdrawal from the bolt, said platehaving sustaining legs designed to bear upon the upper surface of thebase flange of the rail to prevent the plate from turning, said legsbeing adapted to be bent slightly outward whenever it is desired toreadjust the nut upon the bolt.

It is sometimes found desirable to remove the nut from the bolt, and nutlooks as a rule do not provide for this readjustment.

My invention provides for a quick readjustment of the nut Withoutdestroying the efliciency of the nut lock whenever it is again required.

The objects and advantages above referred to may be attained by means ofthe construction illustrated in the accompanying drawing, in which,

Figure 1 is a vertical sectional view taken through the railway rail,the fish plates at the sides of the rail, the nut lock and the nut, thebolt being shown in side view. Fig. 2 is an enlarged perspective view ofthe nut lock removed from the bolt.

' Referring to the drawing the numeral 1 designates a railway rail ofthe usual construction; 2 are the fish plates, also of the usual or anypreferred type.

The plate 3 and the nut 4 may be of the common or usual form.

This bolt lock comprises asheet steel plate 5 of substantiallyrectangular form provided with a bolt opening 6 extending through theplate. Cut from the body of the plate by means of a slit 7, extendingfrom the bolt holes 6 upward, and a curved slit 8 extending from theslit 7 outward, is a spring tongue 9, saidtongue being bent outward fromthe plane of the plate and provided with a sharpened cutting edge 10designed to bite into the inner face of the nut 4 to prevent the nutfrom turning upon the bolt. The usual form of nut is made ofsubstantially soft iron and the steel edge 10 will bite into the metalto prevent the nut from backward movement.

Extending downward from the plate 5 are supporting legs 11 at oppositesides of the plate. These supporting legs rest upon the top of the baseflange of the rail to prevent the plate from turning in use; said legs,however, may bear against any projecting portion with which a nut lockis designed to be used. l/Vhenever it is desired to readjust the nut 4upon the bolt 3 or to loosen the nut on the bolt, the legs 11 may bebent outward from the fish plate, by means of a cold chisel, or similartool, thus permitting the plate 5 to be revolved with the nut 4 inloosening from the bolt. Whenever it is desired again for use the legs11 can be straightened out and the nut lock is again in condition foruse.

From the foregoing it will be obvious that a nut lock made in accordancewith my in vent-ion is simple in construction, can be used with any formof bolt and nut, will hold the nut firmly in adjusted position, willpermit the nut to be removed from the bolt and readjusted withoutdestroying the nut 100 r.

Having thus fully described the invention what is claimed as new is:

The herein described nut lock made from a flat rectangular sheet steelplate having a bolt hole therein, sustaining legs extending down fromopposite sides of the bottom of the plate to rest upon a supportingsurface and to assist in preventing the plate gage and bite into theplane face of an ordinary nut.

In testimony whereof I aifix my signature in presence of two witnesses.
